# How many $$3 \times 3$$ squares can fit inside a rectangle with a height of 36 and a width of 30?

120

Explanation

To calculate how many 3 x 3 squares will fit first find the area of the larger rectangle. Area for a rectangle is height multiplied by width: $$36 \times 30=1080$$. A single $$3 \times 3$$ square has an area of $$3 \times 3=9$$ so to find the number of these squares that will fit in the large rectangle divide the rectangle's area by the square's area:
$$1080 \div 9 = {\rm{ }}120$$
